Actually, for a fascist it's very easy. When words dont really mean anything and your ideology demands no consistency you can say what you want and defend the indefensible. If you think that rational people would see through all that you're right, but their followers arent. They've been trained for over forty years to be led by the nose by their media peer group. Be it conservative news or Facebook posts or green text or their local evangelical demigogue, whatever it is they will be told what they want to hear. Trump is right, and by extention they are right too. And to question it is to put at risk all the relationships they've built up over their lifetime. To be wrong is too risky, so they simply arent. And people like Sean Hannity can say whatever they want without question.
